Application filed June 27, 1916. Serial No. 106,222.

to radiator casings which are provided with dampers operated bya thermostat.

Radiator casing dampers which are provided with automatic operating means are usually operated in one of two ways. The dampers may be connected to an independent source of power under control of a room thermostat, or the thermostat may be directly connected to the dampers, in which case the thermostat is the prime mover. In both forms of construction the lever and rod connections necessary between the dampers and the source of power, are unsightly objects, and it is the practice to build the casing with additional space sufficient to inclose and protect these parts.

In the type of construction to which my invention belongs the thermostat is on the outside of the casing, and is required to be insulated from the radiator sections. This is accomplished by means of a thick insulating wall which of necessity takes up additional space. In certain situations where economy of space is of prime importance, as in oflice buildings and certain classes of apartments, radiator casings, thus enlarged to accommodate working parts and provide heat insulated walls between the radiator sections and thermostat, have not met the space requirements in such buildings, and their field of usefulness has been therefore restricted to locations where space is not a controlling factor. In order that this objection may be in a large part or wholly overcome, and the power transmitting connections may be protected and concealed, I take advantage of the thickness of the heat insulating Wall to house certain parts of the thermostatic device, by forming in the wall a pocket or cavity for receiving these parts, such as the power transmitting means connecting the thermostat and the casingdampers and other associated parts. This arrangement enables the casing to be short ened, thereby effecting economy in space and cost of construction without sacrificing the object of concealing and protecting the unsightly connecting parts and of insulating the thermostat from-the radiator sections.

The thermostatic element may be of any type capable of supplying the necessary power to operate the dampers, but I preferably employ a corrugated collapsible and expa'nsible vessel containing a volatile substance. The power transmitting means which I locate in the recess in the insulating Wall may also be of any type. I preferably .use an adjustable power transmitting mechanism provided with resilient-compensating means, such as disclosed in my U. S. Patent No. 1,186,180, dated June 6, 1916, rearranging some of the parts for sake of compactness.

In order that the invention may be more readily understood. reference is. had to the accompanying drawing which illustrates by way of example one mechanical embodi ment of the invention, but such drawing is intended to assist the description and is not for the purpose of defining the limits of the invention. I v v The drawing shows in elevation a portion of a radiator, and in vertical longitudinal section a radiator casing embodying my improvement.

1 is a portion of a sectional radiator which is provided with a casing, the end wall 2 of Which is provided with a thick layer or layers insulating material 3, such as cork or other equivalent substance, in which is formed a pocket or receptacle 4 shown with a closure 5 secured in place by screws 5. The upper portion of this pocket is open to a hood 6 which rests on top of the casing walls over dampers 7 which control the flow of air passing up and around the heating sections 1. Mounted on the exterior of the insulating wall 2 is a thermostat 8 inclosed in a perforated housing 9. The thermostat shown is of the extensible and contractible corrugated type having a movable other means above. The lower end of lever 11 is also acted on by a tension spring 17, one end of which acts on the lever 11 through rock member 16, and the opposite end of which connects with threaded means 18 adapted to be adjusted by a key-operated stem 19 with which a hand 20 moves to indicate readings on a suitable scale. As the compensating and adjusting means areof the general construction shown in my above patent, reference is had to this patent for detailed information.

lt will be readily seen from the above that the location of the power transmittingmeans, including both adjusting and compensating devices, within the insulating wall secures a reduction of radiator casing space by utilizing space heretofore used by the wall itself without sacrificing the advantages of protection and concealment of these unsightly parts, while effecting economy gt material and cost of manufacture.

Whah is claimed is:

1. in combination, a; damper-controlled radiator casing having an insulating wall in which is formed a pocket, a removable closure for one side of the pocket, a thermostatic element heat insulated by said wall from the radiator, power transmitting connections between said element and the easing dampers housed in. said pocket, and

other means housed in said pocket for ad-- naeaear 4;. in combination, a damper-controlled radiator casing having an insulating wall in which is formed a pocket, a thermostatic element heat insulated by said wall from the radiator, and power transmitting con nections between said element and the'casing dampers housed in said pocket.

5. in combination, a damper-controlled radiator casing having an insulating wall in which is termed a pocket, a removable closure for one side of the pocket, a thermostatic element heat insulated by said wall from the radiator, and power transmitting connections between said element and the casing dampers housed in said pocket.

6. In combination, a damper-controlled radiator casing having an insulating wall in which is formed a pocket, a thermostatic element heat insulated by said wall from the radiator, power transmitting connections between said element and the casing dampers housed in said pocket, and other means housed in said pocket for adjusting and compensating said element.

7. In combination, a damper-controlled radiator casing having an insulating wall in which is formed a pocket, a thermostat carried by the side of said wall remote from the radiator, and operating connections intermediate said thermostat and the casing dampers housed in said pocket.

' 8. In combination, a damper-controlled radiator casing having a wall provided with a thick layer of insulation material in which is formed a pocket, a thermostat carried by the side of said wall remote from the radiator, and operating connections intermediate said thermostat and the casing dampers housed in said pocket.

9. In combination, a damper-controlled radiator casing having a wall provided with a thick layer of insulation material, a thermostat on the side out said wall remote from said radiator, and operating connections intermediate said thermostat and easing dampers inside of said wall.

In testimony whereof specification.
